Problems
Our F.A.Q
  • F.A.Q one question one answer



Composite
A black background ?
  • ATI cards : try without OpenGL (cairo-dock -c) => Drivers aren't correct !
  • Intel cards : some of them work with OpenGL (see the follow section) or try without OpenGL (cairo-dock -c) => Some drivers aren't correct !
  • KDE4 : launch systemsettings and do that : Look & Feel --> Desktop --> Desktop Effects --> Enable Desktop Effects
  • Gnome without Compiz (just with Metacity) : launch gconf-editor, and open apps / metacity / general and enable composing-manager.
  • More details : Composite Manager



OpenGL
  • Intel cards : If you know what this is (not for beginners), try to change your xorg.conf file (/etc/X11/xorg.conf), in Monitor section by
    Section "Monitor"
    Identifier "Configured Monitor"
    Option "AccelMethod" "UXA"
    EndSection
    UXA can be a solution but it's not very stable... So, do a backup of your xorg.conf before doing that ! More details : http://www.glx-dock.org/bg_topic.php?t=2652&pos=20 or http://webupd8.blogspot.com/2009/05/graphic-video-drivers-ubuntu-repository.html.
    • It seems that Intel X3100 graphics cards on Ubuntu Jaunty (ONLY!) can support OpenGL. Check two topics here and here.
    • => Cairo-Dock with OpenGL support seems to be fully supported (without doing any modification) on Ubuntu Karmic (tested 13 Aug 2009 with the last Intel drivers (2:2.8.0-0ubuntu2) and the last kernel (2.6.31-5-generic) on an Eeepc701 while having multiple visual effects and remains fluid!)

  • Nvidia cards : Normally, it works well out of box with property drivers.
    • But if you have this warning message : "cannot find -lGL", try this command in a terminal
      cd /usr/lib/ && sudo ln -s libGL.so.1 libGL.so
    • Or if you have that
      NVIDIA: could not open the device file /dev/nvidiactl (Permission not allowed).
      NVIDIA: Direct rendering failed; attempting indirect rendering.
      . It's maybe because your user isn't linked to the video group. With a text editor (gedit, nano, vim, kate, etc.) modify this file /etc/group :
      sudo nano /etc/group
      and add your user name on the video group :
      video:x:XX:USER
      (where XX is a free number (the last one + 1) and USER is your user name.

  • ATI cards : Sorry but already now (2009 May), ATI drivers are just crappy . But there are many reasons to hope and we may have a real driver one day . So wait and use Cairo-Dock without OpenGL. (cairo-dock -c)

  • But you can use Cairo-Dock with a fake transparency in the System menu in the config panel of Cairo-Dock (or by using with a black wallpaper )



(S)MPlayer
If you have any problem with (S)MPlayer :
    • Try to put the video output to gl2 (in the settings of SMPlayer)
    • Or use this command to launch (S)MPlayer:
      export XLIB_SKIP_ARGB_VISUALS=1
      smplayer &



Others apps based on Qt4 like VirtualBox
It's the same problem that (S)MPlayer.
    • Create a file with the extention ".sh" (launch_virtualbox.sh for example)
    • Add these two lines :
      export XLIB_SKIP_ARGB_VISUALS=1
      virtualbox
    • Change the right execution (Right clic on the file / Properties / Permissions / Execution => or directly :
      chmod +x launch_virtualbox.sh
    • Use this file to execute this app.



Problem with installation / update ?
If you have something like this:
  • trying to overwrite `/usr/share/cairo-dock/default-indicator.png', which is also in package cairo-dock-data
    dpkg-deb: subprocess paste killed by signal (Broken pipe)
  • E: /var/cache/apt/archives/cairo-dock_2.0.0_all.deb: tentative de remplacement de « /usr/share/cairo-dock/icon-mouse.png », qui appartient aussi au paquet cairo-dock-data.


You have to do that :
sudo apt-get remove cairo-dock* --purge
sudo apt-get install cairo-dock cairo-dock-plug-ins




Problem to change/save your configuration ?
It's maybe a permission problem:
chmod u+rwx -R ~/.config/cairo-dock/




Problem with a gauge ?
If you have an output like this:
xterm -e ' wget "http://themes.glx-dock.org/gauges/turbo-night-fuel/turbo-night-fuel.tar.gz" -O "/tmp/cairo-dock-net-file.AfLFEO" -t 2 -T 5'

Just change gauges in your enabled plugins by those beginning with a capital (eg. turbo-night-fuel => Turbo-night-fuel).



Problem with wifi applet ?

It's a problem of right acces to iwconfig command.
With root right (root = sudo for Ubuntu for example), do this commands in a terminal:
chmod u+x /sbin/iwconfig # or "chmod 755 /sbin/iwconfig" if it's doesn't work
ln -s /sbin/iwconfig /usr/bin/iwconfig




Problem when Cairo-Dock is launched automatically ?

If you have some bug when Cairo-Dock is launched automatically at startup and not when it's launched manually : Try to launch it with a delay.

In your session manager (help here), use this command :
sh -c "sleep 15 && cairo-dock -o"

Change any parameters according to your configuration (here we have 15 seconds and Cairo-Dock with OpenGL)



A message at startup
